ELECTRIC HEATER.

To all whom it rhay concern Be it known that we, FRANK KUHN and FRANK E.SHAILOR, citizens of the United States of America, residing at Detroit,in

the county of Wayne and State of Michigan, have invented certain new anduseful I'mprovements in Electric Heaters, of which the following is aspecification, reference being had therein to the accompanying drawings.

The invention relates to electric heaters of that type designed for usefor various cooking operations, and the invention comprises the novelconstruction as hereinafter set forth.

In the drawings: Figure 1 is a plan view of the heater; Fig. 1 is a viewshowing the reflector plate removed but in position for engagement withthe heater; Fig. 2 is a vertical cross section through the heater; andFig. 3 is a perspective view of the reflector plate detached.

A is a suitable base, above which is ar- I ranged an annular frame Bsupported upon a pair of spaced legs C.

' D is an electrical'heating unit within the frame B, preferablycomprising an insulator ring E and naked resistor coils F extending backand forth across said ring.

G is a grating arranged across the top of the annular frame Eand'serving to support the toast or other food to be heated.

With the construction as thus fardescribed, the heat radiated from theresistor F will pass both upward and downward. The space between thering B and the base A is sufficient to provide access to the downwardlyradiated heatfrom the resistor F, so that toasting or broilingoperations may be performed below as well as above the resistor. Thisadds to the capacity of the heater, and by making the upper face of theplate A a heat-reflecting sur ace, injury to the table or support isprevented. Where, however, the upwardly-radiated heat alone is utilizedthere is danger of an over-heating Specification of Letters Patent.

of the base, and furthermore, the efliciency 1s not as great as wherethe heat-reflecting surface is placed nearer to the resistor.

With the present improvement the heater 1s adapted for use as either adouble or a single-faced resistor, by the provision of a removablereflector plate arranged above the base and adjacent to the lower edgeof the ring B. This reflector plate H is preferably formed of sheetmetal having a bright upper surface; and depending legs I, welded orotherwise secured to the lower face of said plate, serve to support itabove the base A, as shown in Fig. 2. Thus when the plate H is inposition the downwardly-radiated heat from the resistor is interceptedand reflected directly upward to reinforce the up wardly-dirccted raysfrom the resistor. Whatever heat is absorbed by the plate H and isradiated downward therefrom will be intercepted by the base plate A, andthus overheating of said base or the table upon which it is supportedwill be prevented.

The plate H may be inserted between the supporting legs or standards C,for the ring B and'shoulders H on opposite sides of the plate, adaptedto abut against said standards, serve to position the parts. Thus theheater is adapted for either throwing all of the heat upward or wheredesired for using both the upward and downward radiation, it beingmerely necessary in the latter case to withdraw the plate H.

What we claim as our invention is 1. In an electric heater, thecombination with a base, a ring spaced there above, spaced standards forsupporting said ring upon said base and a heating unit extending acrosswithin said ring, of a removable reflector plate insertible between saidstandards and legs upon said reflector plate for supporting the samefrom said base substantially in the plane of the lower edge of the ring.
